✦ Synopsis

We extend Berenger's perfectly matched layers PML to ( ) conducti¨e media. A finite-difference᎐time-domain FDTD algorithm with PML as an absorbing boundary condition is de¨eloped for solutions of Maxwell's equations in inhomogeneous, conducti¨e media. For a perfectly matched layer in a conducti¨e medium, an additional term in¨ol¨ing the time-integrated electric field has to be introduced to account for the coupling between the loss from the PML and the normal conduction loss. This absorbing boundary condition is pro¨en to be highly effecti¨e for the absorption of outgoing wa¨es at the computational edge e¨en when a dipping interface intersects the outer boundary. The algorithm is ¨alidated by analytical solutions, and is also compared with Liao's absorbing boundary condition. Numerical results for subsurface radar measurements are shown to demonstrate the applications of this method.

## Abstract A modified __Z__‐transform‐based algorithm for implementing the D‐H anisotropic perfectly matched layer (APML) is presented for truncating the finite‐difference time‐domain (FDTD) lattices. The main advantage is that, as compared with the previous __Z__‐transform‐based implementation fo

## Abstract The aim of this communication is to correct potential misunderstandings about the PMLs (which are called the MIPMLs) based on __D__–__H__ (__E__–__B__ or __D__–__B__) fields. In fact, the motivation for developing the MIPMLs is to establish accurate and efficient PML absorbers for gener
